Design, Modeling and Simulation of a Buffer and Injection Unit for Deep Sea Mining
Karlsen, Bjørn Olav Ljosland; Storli, Mari (Master thesis, 2022)This thesis presents a design of a buffer and injection unit used in deep sea mining. The design process has presented a promising concept, that has been validated through modeling and simulations. The main task for the ... -
Development of 3D anti-Swing control for hydraulic knuckle boom crane
Jensen, Konrad Johan; Ebbesen, Morten Kjeld; Hansen, Michael Rygaard (Journal article; Peer reviewed, 2021)In this paper, 3D anti-swing control for a hydraulic loader crane is presented. The difference between hydraulic and electric cranes are discussed to show the challenges associated with hydraulic actuation. The hanging ... -
Development of Point-to-Point Path Control in Actuator Space for Hydraulic Knuckle Boom Crane
Jensen, Konrad Johan; Ebbesen, Morten Kjeld; Hansen, Michael Rygaard (Journal article; Peer reviewed, 2020) -
Motion Control of Hydraulic Winch Using Variable Displacement Motors
Moslått, Geir-Arne (Doctoral Dissertations at the University of Agder; no. 305, Doctoral thesis, 2020)To compete in the open market of the offshore crane industry, it is imperative for the manufacturer to continuously improve crane operability. In this context, the crane operability is expressed by means of a so-called ... -

Practice for determining friction in hydraulic winch systems
Moslått, Geir-Arne; Hansen, Michael Rygaard (Peer reviewed; Journal article, 2020)This paper presents a method for estimating friction in hydraulic active heave compensated (AHC) offshore winches. The method is a two-step approach where the first step is to model the friction loss in the hydraulic motors ... -
Steady state counterbalance valve modeling with the inuence of synthetic ester oils using CFD
Jakobsen, Jannik Hartwig; Hansen, Michael Rygaard (Peer reviewed; Journal article, 2020)This study looks in details at the effects of synthetic esters being applied to a counterbalance valve from the perspective of a system engineer. There is limited literature on the subject of applied synthetic esters and ...
